To group data in a PivotTable by a specific column, which step should you take first?

The first step to group data in a PivotTable by a specific column is to click on the column that you want to group. This action is essential because it allows Excel to recognize which specific data you're interested in manipulating. By selecting the column, you enable Excel to understand the context of the grouping action you're about to utilize.

Once the appropriate column is selected, you can proceed with grouping it in the PivotTable options. This step is crucial as it sets the framework for how the data will be aggregated or categorized, which is fundamental when analyzing data trends or summaries in a PivotTable.

The other options, while they may involve steps related to interacting with a PivotTable, do not directly initiate the grouping process. Groups can be created only after the specific column of interest has been selected.
